Instead, they are merely examples of apparatus and methods consistent with aspects related to the disclosure as recited in the appended claims.

Currently, more and more users are using a balance car instead of walk. However, driving the balance car is not allowable in some areas for the sake of safety, so a user may need to drag the balance car manually if he wants to move it to a place in these areas, which brings troubles to the user's operation and requires a lot of physical strength.

Embodiments of the present disclosure provide a method for controlling a balancer car. The method can be used in a program, a system or an apparatus for controlling the balancer car, while an execution body applying to the method may be a balancer car or a terminal connected with the balancer car.

The embodiment of the present disclosure provides a method for controlling a balancer car. Referring to FIG. 1, FIG. 1 is a flowchart illustrating a method for controlling a balance car according to an exemplary embodiment.

As shown in FIG. 1, the method includes step S101 to step S102

In the step S101, a target navigation marker used for navigating the balance car is detected.

In an embodiment, the target navigation marker includes one or more of a graphic navigation marker, an audio navigation marker, a video navigation marker and an infrared navigation marker, and is used to indicate at least one of a traveling direction and a traveling speed of the balancer car.

In the step S102, the balance car is controlled to travel according to the target navigation marker when the target navigation marker is detected.

By detecting a target navigation marker used for navigating the balance car, the balance car can be controlled intelligently to travel according to the target navigation marker when the target navigation marker is detected, without requiring a user to drive the balance car, so that an intelligent control to the balance car can be realized. Accordingly, the user does not need to drag the balance car manually if he cannot drive the balance car, bringing convenience to the user.

The embodiment of the present disclosure provides a method for detecting a target navigation marker used for navigating the balance car, further detailing the step S101 illustrated in FIG. 1.

Referring to FIG. 2, FIG. 2 is a flowchart illustrating that a target navigation marker used for navigating a balance car is detected according to an exemplary embodiment.

As shown in FIG. 2, the step S101 illustrated in FIG. 1 is implemented, that is, the target navigation marker used for navigating the balance car is detected, through the following steps.

In step Al, a candidate marker on a road where the balance car is located is detected.

The candidate marker can be all kinds of markers drawn on the road that may represent the navigation marker, such as various lines and icons.

In step A2, attribute information of the candidate marker is obtained in response to the candidate marker being detected.

The attribute information is used to represent all kinds of attributes of candidate markers, such as set position, color, length and width.

In step A3, the target navigation marker is determined according to the attribute information, a similarity between the attribute information of the target navigation marker and predetermined attribute information is greater than a predetermined similarity. In an embodiment, the predetermined attribute information includes standard attribute information of the target navigation marker that is previously preset.

Some disturbing objects may be present on the road where the balance car is located, or multiple navigation markers with different attribute information can be provided on the road. Thus, the candidate marker on the road where the balance car is located can be detected first when the target navigation marker is being detected. An desired target navigation marker can be determined from the candidate marker, after the candidate marker is detected.

For instance, obtaining of a yellow navigation marker is taken as an example. The candidate marker on the road where the balance car is located is detected. The attribute information of the candidate marker is obtained in response to the candidate marker being detected, that is, the color of the candidate marker is obtained. The color similarity between the color of the candidate marker and yellow is obtained, and then the candidate marker with color similarity greater than the predetermined similarity is obtained and determined as the target navigation marker.

Moreover, if there are multiple candidate markers, the similarity between whose attribute information and the predetermined attribute information is greater than the predetermined similarity, the candidate marker whose attribute information has maximum similarity with the predetermined attribute information among the multiple candidate markers can be determined as the target navigation marker.

In an embodiment, the target navigation marker includes at least one of a graphic navigation marker, an audio navigation marker, a video navigation marker and an infrared navigation marker.

The target navigation marker may indicate at least one of a traveling direction and a traveling speed.

The target navigation marker includes at least one of above described markers, which enriches the navigation mark, so that the balance car can travel according to different types of navigation markers. Moreover, the target navigation marker can indicate at least one of the traveling direction and the traveling speed, thus the balance car can be controlled intelligently to travel according to indicated traveling direction and indicated traveling speed, and the user is greatly facilitated.

Moreover, the traveling speed can be low to ensure driving safety. If the traveling speed is lower than or equal to the user's walking speed, it can follow the user and travel automatically according to the target navigation marker.

The embodiment of the present disclosure provides another method for detecting a target navigation marker used for navigating the balance car, further detailing the step S101 illustrated in FIG. 1. In the method, the target navigation marker includes the graphic navigation marker, and the balance car is provided with a camera, which can be installed on any place in the balance car, such as on the base of the balance car.

Referring to FIG. 3, FIG. 3 is a flowchart illustrating that a target navigation marker used for navigating a balance car is detected according to another exemplary embodiment.

As shown in FIG. 3, the step S101 illustrated in FIG. 1 is implemented, that is, the target navigation marker used for navigating the balance car is detected, through the following steps.

In step B 1, a road image of the road where the balance car is located is obtained by the camera.

In step B2, the graphic navigation marker is detected by performing recognition on the road image.

If the target navigation marker includes the graphic navigation marker and the balance car is provided with a camera, the road where the balance car is located can be shot by the camera to obtain the road image when the graphic navigation marker is obtained, and then the road image can be performed recognition, thus the graphic navigation marker on the road can be detected accurately.

Moreover, the balance car may be also provided with a lighting device such as a lamp. When the road image is obtained, the lighting device can be turned on if current ambient brightness is lower than a predetermined ambient brightness, so that the current ambient brightness can be higher than or equal to the predetermined ambient brightness. Thus the road image with high resolution and definition can still be shot under low ambient brightness, and it benefits that the road image can be performed recognition better so that the graphic navigation marker can be detected accurately.

In an embodiment, the graphic navigation marker includes at least one of a navigation icon on the road, a navigation icon on a signpost and a navigation icon on a building near the road.

The graphic navigation marker on the road where the balance car is located can be at least one of a navigation marker drawn on the road, a navigation marker on a signpost near the road (for example both sides of the road) and a navigation marker on a building near the road (for example on the wall of a building along the road). The graphic navigation can include a navigation line, a navigation guidance arrow, an icon, characters, and the like.

In an embodiment, the target navigation marker includes the navigation icon on the road, and the navigation icon on the road includes a navigation line on the road.

The attribute information includes at least one of set position, color, length and width.

The navigation icon on the road can include a navigation line on the road and the attribute information can include at least one of set position, color, length and width, so that when the target navigation marker is determined according to the attribute information, the similarity between the attribute information and the predetermined attribute information can be derived by determining whether the set position is within a preset position, whether the color of the candidate marker is same with a preset color, whether a continuous length of the candidate marker exceeds a preset length, or whether a width of the candidate marker exceeds a preset width, or the like. Then the target navigation marker can be determined accurately according to the attribute information of the candidate marker.

The embodiment of the present disclosure provides a method for controlling the balance car to travel according to a target navigation marker, further detailing the step S102 illustrated in FIG. 1.

The step S102 illustrated in FIG. 1 is implemented, that is, the balance car is controlled to travel according to the target navigation marker, through the following steps.

The balance car is controlled to travel according to the navigation line on the road, which can be navigation lines of various colors drawn in advance, such as white, black, red and the like.

When the balance car is controlled to travel according to the target navigation marker, if the target navigation marker includes a navigation line on the road, the balance car can be controlled intelligently to travel itself according to the navigation line on the road, so that the balance car can be navigated by the navigation line on the road.

Referring to FIG. 4, FIG. 4 is a flowchart illustrating that a balance car is controlled to travel according to a target navigation marker according to an exemplary embodiment.

As shown in FIG. 4, in an embodiment, the step S102 illustrated in FIG. 1 is implemented, that is, the balance car is controlled to travel according to the target navigation marker, through the following steps.

In step C1, the target navigation marker is controlled to be presented in the road image.

The balance car can be controlled to travel according to the target navigation marker such that the target navigation marker is always presented in the road image. Thus the balance car can be ensured to travel automatically without deviating from the target navigation marker.

Moreover, when it is controlled such that the target navigation marker is always presented in the road image, it had better been controlled such that the target navigation marker is always presented in the middle of the road image, thus the balance car can be sufficiently ensured to travel without deviating from the target navigation marker

In an embodiment, if the target navigation marker includes respectively an audio navigation marker, a video navigation marker and an infrared navigation marker, these navigation markers can be detected for the balance car via a signal sent by a target device, which can be a device wired or wireless connected with the balance car and located at any place. The target device may interact with the balance car and send an audio signal including an audio navigation marker, a video signal including a video navigation marker or an infrared signal including an infrared navigation marker to the balance car, so that the audio navigation marker can be detected by performing recognition on the received audio signal, the video navigation marker can be detected by performing recognition on the received video signal, the infrared navigation marker can be detected by performing recognition on the received infrared signal, and then the balance car can travel according to the detected audio navigation marker, the detected video navigation marker, the detected infrared navigation marker. For instance, the target device can be positioned at the road where the balance car is located, and send an infrared signal including an infrared navigation marker or an audio signal including an audio navigation marker to the balance car when the balance car is detected to be approaching, so that recognition can be performed on the infrared signal and audio signal by the balance car, then the infrared navigation marker or the audio navigation marker can be detected, and the balance car can travel according to the infrared navigation marker or the audio navigation marker.

To allow the user to learn about these markers, these makers can be output by means of audio, text or image.

In an embodiment, the graphic navigation marker can also be output by means of displaying an image on a device.

Referring to FIG. 5, FIG. 5 is a flowchart illustrating that a balance car is controlled to travel according to a target navigation marker according to another exemplary embodiment.

As shown in FIG. 5, the step S102 illustrated in FIG. 1 is implemented, that is, the balance car is controlled to travel according to the target navigation marker, through the following steps.

In step 501, a travelling instruction is obtained according to the target navigation marker.

In step 502, the balance car is controlled to travel according to the travelling instruction, which is used to indicate at least one of a traveling direction and a traveling speed of the balancer car.

When the balance car is controlled to travel according to the target navigation marker, a travelling instruction can be obtained according to the target navigation marker, and then the balance car can be controlled intelligently to travel automatically according to the travelling instruction.

In an embodiment, a detailed process for obtaining the travelling instruction is described as follows.

When the target navigation marker includes a graphic navigation marker, the travelling instruction can be obtained by performing graph recognition on the graphic navigation marker. For instance, the travelling direction can be obtained by performing recognition on the direction where a guidance arrow in the graphic navigation marker is pointed to, and the travelling speed can be obtained by performing recognition on a speed limit sign in the graphic navigation marker.

When the target navigation marker includes an audio navigation marker, the travelling instruction can be obtained by performing audio recognition on the audio navigation marker. For instance, the travelling direction can be obtained by performing recognition on voice information (for example, the voice information indicative of turning left or turning right) used to indicate a direction in the audio navigation marker by means of voice recognition technology, and the travelling speed can be obtained by performing recognition on voice information (for example, a top speed of the balance car is XX meter per second) used to indicate speed in the audio navigation marker by means of voice recognition technology.

When the target navigation marker includes a video navigation marker, the travelling instruction can be obtained by performing audio recognition or graph recognition on the video navigation marker. For instance, the travelling direction can be obtained by performing recognition on voice information or image (for example, characters including a indicated direction or an image including a guidance arrow) used to indicate a direction in the video navigation marker, and the travelling speed can be obtained by performing recognition on voice information or image (for example, an image including speed) used to indicate a speed in the video navigation marker.

When the target navigation marker includes an infrared navigation marker, the travelling instruction can be obtained by performing infrared recognition on the infrared navigation marker. For instance, the travelling direction can be obtained by performing recognition on infrared signals used to indicate a direction in the infrared navigation marker, and the travelling speed can be obtained by performing recognition on infrared signals used to indicate speed in the infrared navigation marker.

The embodiment of the present disclosure provides another method for controlling the balance car to travel according to a target navigation marker, further detailing the step S102 illustrated in FIG. 1.

Referring to FIG. 6, FIG. 6 is a flowchart illustrating that a balance car is controlled to travel according to a target navigation marker according to still another exemplary embodiment.

As shown in FIG. 6, the step S102 illustrated in FIG. 1 is implemented, that is, the balance car is controlled to travel according to the target navigation marker when the target navigation marker is detected, through the following steps.

In step S601, when the balance car travels to a target intersection and there are at least two target navigation markers at the target intersection, a final target navigation marker can be determined by at least one of the following selection manners of a navigation line. Herein, the target intersection can be any intersection on the road where the balance car is located.

In step S602, the balance car is controlled to travel according to the final target navigation marker.

The selection of the navigation line include following manners.

The final target navigation marker can be determined according to a preset travelling direction corresponding to the target intersection, which may be a travelling direction that is preset according to a travelling destination of the balance car.

When there are multiple target navigation markers at the target intersection, in order that the final target navigation marker can be determined accurately, according to the travelling direction corresponding to the target intersection, the target navigation marker indicating the travelling direction can be determined as the final target navigation marker. Then the balance car can be controlled to travel automatically according to the target navigation marker including this travelling direction.

Alternatively, a selection instruction of travelling direction is received, and the final target navigation marker is determined according to the selection instruction of travelling direction.

When there are multiple target navigation markers at the target intersection, the target navigation marker that the user expects (that is, the target navigation marker selected according to the selection instruction of travelling direction) can be selected as the final target navigation marker according to the selection instruction of travelling direction. Then, the balance car can be navigated by the target navigation marker selected by the selection instruction of travelling direction, and travel automatically according to the travelling direction and travelling speed that the user expects.

Alternatively, it is determined that whether there is a prestored historic selected record of a navigation line corresponding to the target intersection.

When there is a prestored historic selected record of a navigation line, the final target navigation marker can be determined according to the historic selected record of the navigation line.

When there are multiple target navigation markers at the target intersection, in order that the final target navigation marker can be determined accurately, it is determined that whether there is a prestored historic selected record of a navigation line corresponding to the target intersection. If yes, according to the historic selected record of a navigation line, the historic navigation marker which is used most frequently, used greatest number of times or most recently used can be determined as the final target navigation marker. Then the balance car can be controlled to travel automatically according to the most commonly used target navigation marker or the most recently used target navigation marker.

Moreover, the above embodiments can be implemented individually or in combination.
